Double combining diacritics

Why are so few double combining diacritics included in Unicode? Also, why
these particular ones? (U+0360 COMBINING DOUBLE TILDE, U+0361 COMBINING
DOUBLE INVERTED BREVE, U+0362 COMBINING DOUBLE RIGHTWARDS ARROW BELOW)

Is the general consensus that this kind of symbols belong more properly to
rich text with complex layout control (so as to accomodate symbols that
apply to larger groups of characters)? Is there the possibility that more
of them could be encoded in the future?

This message was prompted by a book that uses an arc below pairs of
letters, as well as its spacing variant (which is encoded, U+203F
UNDERTIE). Well, both of them are underties (Greek hyphens) but
they're used in different ways...
